Startle produces early response latencies that are distinct from stimulus intensity effects.
TL;DR: The presented data show that RTs associated with a startle response are separate from stimulus intensity facilitated responses, and this startle facilitation is more highly associated with sternocleidomastoid electromyographic (EMG) activity, rather than the EMG from the widely used startleresponse indicator muscle orbicularis oculi.

Frequency response of human vestibular reflexes characterized by stochastic stimuli
TL;DR: Findings strongly support the vestibular origin of the lower limb muscles evoked by SVS and support the view that the biphasic muscle response is conveyed by two distinct physiological processes.

Modulation of human vestibular reflexes with increased postural threat

TL;DR: The results support the idea that the manner in which vestibular information is processed is altered when people are exposed to a threat to their balance, and this altered processing may explain why normal balance behaviour is different in threatening scenarios.

TL;DR: In this article, motor unit (MU) activity in the medial (MG) and lateral (LG) gastrocnemius muscle and the soleus (SOL) in standing balance and voluntary 28 isometric contractions was recorded in seven subjects with 30 wire electrodes in the triceps surae.

TL;DR: It is suggested that the wider bandwidth of head-neck biomechanics requires a vestibular influence on neck-muscle activation across a larger dynamic range than lower limb muscles, and that pathway-dependent neural filtering contributes to these muscle-specific responses.
